IMPROVEMENT IN BATfi-TUBS.

Specification forming part of Letters Patent No. dated June 1875;application filed To almhom it may concern:

Be it known that I, EPHRAIM CHAMBER LAIN, of Weymouth, in the county ofNorfolk, and State of Massachusetts, have invented a new and usefulImprovement for an Apparatus for Bathing Purposes; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, which form apart of this specification.

The object of this invention is to construct an apparatus large enoughfor bathing purposes, and made in such a manner that it can be folded inasmall space ior'transportation, or putaside for further use after theoperation of bathing is dispensed with, constituting thereby a portablebath-tub. And it consists in the construction and operation, as will befully hereinafter described.

In the drawings, Fig. l is an isometrical view of bath-tub when open andready for use. Fig. 2 is a side elevation when the same is closed orpacked together. Fig. 3 is an end elevation of Fig. 1.

A is the base upon which the tub rests, and is made of wood or othersuitable material. A is the upper frame-work, constructed on its innerside, to conform to the shape of the tub. B B are two supporting endshinged to the base A at b b, so as to permit them being doubled entirelyunder the bottom, as shown in Fig. 2. G O are two auxiliary supportspivoted on the side and middle of base A at 0. hen the tub is intendedto be open, the several supports-viz: B B and O G-are opened out and upand placed in their respective supporting positions under the upperrigid framework A. D is a flange upon the upper side of base A, to whichthe tub is attached at its May 12, 1875.

bottom or lower end. E is the rubber canvas or water-tight material, ofany kind that will permit of its being folded without destroying itsutility, the upper part of which is attached to frame-work A, and uponits being forced upright forms the tub. e is a small hook pivoted on theend of base A to catch hold of pin 6 in the end of the upper frameworkA, when the two parts A and A, are brought together, and serves to holdthe two parts A and A securely together when the tub is in position,folded for transportation or otherwise. d are knobs or feet on the underside of bottom of tub or base A, which bottom is provided with ametallic outlet for the water. The bottom of the tub proper, on theinside, is lined with a coating of rubber or a flooring of zinc, as inordinary bath-tubs, but I prefer the rubber coating.

I am aware of the patents of John G. Clapp, October 22, 1867, No.69,968, and John P. lRider, July 6, 1869, No. 92,364, and disclaim 1cm.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In combination with flexible waterproof bath-tub E, base A, upperframe-work A, flange D, attached in the form and manner substantially asdescribed.

2. In combination with bath E, supportingends B B, auxiliary supports 0O, hook 0, pin 0, knobs d, constructed and arranged substantially in theform and manner and for the purposes described.
